Mars rover drills, sees planet’s true colors

Mars may have a lot of orangey dust flying around, but now that a rover has retrieved a sample by drilling a rock there, scientists believe the Red Planet may have another color beneath the surface.
The two-ton Mars rover Curiosity, which has been exploring Gale Crater since its miraculous landing on August 6, has become the first robot to drill into a rock to collect a sample on Mars, scientists reported Wednesday. Chemical analyses are still to come, but for now the big news is that the material from the drill appears to be gray.
